I ordered these curtains because they were the only ones I could find in silver. I thought it was a perk that they are "thermal backed". I just received these curtains and much to my dismay, they look and feel like a shower curtain! They sound like plastic and look like plastic. As for the "thermal back", that is a joke. I have another set of curtains with thermal backs in my living room and they are thick and block not only the draft, but sunlight too. These curtains do neither of those things. I would return these curtains BUT I have no window coverings at the moment, so I'm going to keep them up until I find a better solution. I should have known they'd be plastic-like since they only cost $xxx!
